By a small margin (55% to 45%) respondents in our Quick Poll! thought the recent mass murder on the campus of Virginia Tech made the case for more gun controls rather than fewer. The percentages swung back and forth each day, never getting far from an even split that roughly reflects nationwide ambiguity on the issue. If Cho had not had a gun, he probably would not have killed anyone, but if others near him during his murder spree had carried guns, he probably would not have killed nearly so many people. The debate goes on.
